“…The archaeometric study conducted on the archaeological finds collected in the Muricelle site suggests that the villa and the surrounding area were active in the Imperial period [3,5]. Indeed, the analysed glasses, despite the recycling, can be considered as being produced in both Levantine and Egyptian primary workshops, in agreement with the results obtained by various authors [6][7][8][9][10][11][12][13][14][15] on the coeval finds from different Roman archaeological sites dated to the first-third century AD.…”

“…As regards the major element concentrations, the samples show SiO2 content varying from 68.72 to 71.35 wt%, and Na 2 O from 16.29 to 19.62 wt%, in addition values of both MnO and K 2 O are below 1.50 wt.%. These results indicate the natron (a sodium carbonate mineral compound abundant in some evaporitic basins) as the unique flux employed during the glassmaking production [4] confirming, as deduced from the archaeological investigations [3,5], that the glass finds of Muricelle site fit perfectly into the Roman glass composition [6][7][8][9][10][11][12][13][14][15][16][17]. To understand the origin of raw materials and the technology of production employed in the Muricelle glass, our results were compared with bibliographic data of the glass productions of the Roman Imperial period (firstthird century AD).…”

Muricelle is an archaeological site located near Cosenza in Calabria (Italy), dated between the first century AD and the Late Antiquity. In Muricelle, numerous archaeological finds have been recovered including pottery, coins, metallic, glass and marble artefacts. In the present study we will illustrate the results obtained on seventeen glass finds, ten amphorae fragments and ten bricks. The petrographic and chemical characterization of the artefacts was undertaken using different analytical methodologies well known in the archaeometric field. Seven local clayey samples, collected from local outcrops were, also, analysed to define their characteristics as potential raw materials for the brick production. The archaeometric approach applied in the study provided important information contributing to reconstruct the archaeological context related to the Muricelle site.

“…As mentioned previously, titania and alumina are among the most important oxides to study the origins of the silica source. With the presented combination of oxides, it is possible to create a chart where the mineralogical characteristics of the silica raw material is related to the glass composition, namely the quartz content (SiO 2 ), the feldspar contribution (Al 2 O 3 ) and the heavy minerals contribution (TiO 2 ) [40,41]. This relation suggests that the group of eight samples marked with an oval dashed line (designated Group 1) and which represents the majority of production remain samples with very similar green/bluish hues are also very similar in terms of the composition of the silica source, strongly suggesting that these glass samples were made from the same source of silica.…”

Calle Horno del Vidrio—Preliminary Study of Glass Production Remains Found in Granada, Spain, Dated to the 16th and 17th Centuries

A set of 14 glass fragments and production remains dated to the 16th and 17th centuries was collected during rescue archaeological works conducted in Granada, Spain, and was characterised by µ-PIXE. This preliminary study constitutes the first analytical approach to glass manufacturing remains from a Spanish production dated to the early-modern period. µ-PIXE allowed for the quantification of major, minor and some trace elements of the glass fragments. It also allowed mapping the elemental distribution on the fragments that were identified as an interface of crucible/glass. This analysis constitutes an evaluation of the ionic exchange between glass and crucible. The glass colours vary from the natural green and blue hues to completely colourless samples. The results show that the majority of the glass samples are of soda-lime-silicate composition, and only one proved to be of a potassium-rich composition. From this, one can hypothesise that glass rich in sodium (following the Mediterranean tradition) and potassium-rich glass (following a central and north European tradition) were both locally produced. Since this location was known as la Calle Horno del Vidrio (Glass Furnace Street) and several production evidences were found, it is highly probable that an artisanal glass production existed in this area.

“…This can be put in direct relation with various Roman sites where antimonydecoloured and HIMT glass were also considered to be of Egyptian origin, while the manganese-decoloured glass was generally attributed to a Levantine provenance (Gliozzo 2017;Nenna 2014;Schibille et al 2016b). The provenance and supply patterns at Oudenburg would thus be the same as in France (Gratuze n.d.), Cyprus (Ceglia et al 2017), Croatia (Coutinho et al 2017), Turkey (Rehren et al 2015) and Italy (Gallo et al 2013;Maltoni et al 2016;Silvestri et al 2008). In the northwestern provinces (Tienen and Maastricht), i.e.…”

“…During the last decades, material science methods were extensively applied in archaeological glass research. Involving a varied geographical range, recent research focuses on regions scarcely explored so far (Cholakova et al 2016;Coutinho et al 2017; de Juan Ares and Schibille 2017). The military camp of Oudenburg, Belgium, has five neatly dated successive building phases between the end of the second and the beginning of the fifth century AD (Vanhoutte 2007).…”

This paper presents the analysis of decoloured and naturally coloured glass from well-dated contexts in the southwest corner of the Roman fort at Oudenburg (Belgium) ranging from the late second to the early fifth century AD. The aim is threefold. First, provide comparative material in the study of glass consumption from the northwestern provinces of the Roman Empire. Secondly, evaluate possible diachronic shifts in the applied decolourizing agent to produce colourless glass as to assess potential correlations between glass production recipes, provenance and chrono-typology. Finally, provide an added value to the research of glass recycling and mixing in the Roman imperial period. Nine subgroups are distinguished based on their chemical composition determined by LA-ICP-MS: Sb-only, two groups of Mn-only, four groups of mixed Mn-Sb, HIMT and one glass without any decolouring agent. The Sb-decoloured glass is used in the earliest phases and can be attributed to an Egyptian provenance. The two subgroups of Mn-glass likely come from different provenances: one from Egypt and the other later one from the Levant. Most of the glass shows high marks of mixing based on high trace elements concentrations and the simultaneous presence of antimony and manganese. Inhomogeneous mixing of manganese and antimony was also detected through μXRF. One Mn-Sb subgroup likely comes from mixing antimony glass with HIMT. The obtained results help better recognise the shifts in applied glass recipes throughout the Roman imperial period and improve our understanding about the mixing and recycling of glass to supply a Roman military camp.
